Sheet format will not change, no matter what

No matter what I try, the page looks the same. I've tried switching to a random format, which worked, but not switching back to the current version of the sheet format. I've named a copy of the new sheet format a different name and switched to that, but no dice. I've tried reloading, but nada. I've created several new .slddrt files, but none of them have any effect on this blasted drawing.

No, I don't believe I've ever run into a situation where I couldn't change sheet formats. When I get really weird behavior it's usually a sign that it's time to re-boot my computer. I assume you've tried that?

In your document properties do you have the "Use Different Sheet Format" box checked? What version and SP are you running? I'm running 2015 SP3 and we are having the same issue here. Working on updating templates for EPDM rollout and this is a critical issue for that! I have more testing to do but just sent an Rx to our VAR for it as they were quite confused trying to make it work also. While I was recording the Rx video I thought that I might try and change what the "sheet 2" default was as that was what I was stuck on after changing to it. So I went to that and tried to just un-check it first, and that allowed me to then go to ANY sheet format I wanted (A/B/C/D size sheet 1 and sheet 2). Then I turn it back on and the same behavior comes back where anything I select it goes to the one specified in the Doc Properties.

Give that a try if you do have it checked and let me know. I'm very curious if that is the culprit for you too.

Chris - Same thing happened to me a few years ago, big issues and a lot of frustrations, however on my end it was all self inflicted, re-named files and ended up with a huge mess. Not saying you did the same thing or even close, but really it sounds like operator error somewhere. Did you share it with your VAR?

Could you take a snap shot of your System Options and file locations, (like below)???

Surely there is something not pointing to the correct file or folder etc...

I started working on SW 2011, and I have seen this issue for all versions after that till SW2014.

(Right now, I work in SW 2014 SP 5.0)

Our company is switching to a new PDM, and we thought to switch the templates too, as we have very old drawings which have to be updated - and this issue makes it more difficult. But you could write a macro which does this job for you (switching between formats) - only that you need to create a sheet format in a different size just for this purpose (even though you won't use this!)

I know this is a little old but I just had the same issue. I tried to change the sheet size through sheet properties and it completely destroyed my drawing. Not only did the sheet size not change, it deleted the entire sheet format of what I was working on. And there's no way to undo that. And then it crashed.

I've done this many times in other SW version and never had this problem. I'm really not liking this new version.
